A61B 5/349

Detecting specific parameters of the electrocardiograph cycle

Introduced: January 2021

Full Title

Full titles differ between systems:

IPC:

Measuring for diagnostic purposes; Identification of persons > Detecting, measuring or recording bioelectric or biomagnetic signals of the body or parts thereof > Modalities, i.e. specific diagnostic methods > Heart-related electrical modalities, e.g. electrocardiography [ECG] > Analysis of electrocardiograms > Detecting specific parameters of the electrocardiograph cycle

CPC:

Measuring for diagnostic purposes (radiation diagnosis A61B6/00; diagnosis by ultrasonic, sonic or infrasonic waves A61B8/00); Identification of persons > Detecting, measuring or recording bioelectric or biomagnetic signals of the body or parts thereof > Modalities, i.e. specific diagnostic methods > Heart-related electrical modalities, e.g. electrocardiography [ECG] > Analysis of electrocardiograms > Detecting specific parameters of the electrocardiograph cycle

IPC and CPC are identically structured here. All 11 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2021.
